Description

Textile Weaving Machine for Water Jet Looms {WEAVING DEVICE OF WATER JET LOOM}

The present invention makes the body by shortening the distance from the fastener in which the weft yarn is interwoven when weaving the fabric using Water Jet Loom to the Friction Roller located at the part where the fabric is wound. Minimizing the bumping phenomenon of the fabric during acupuncture, so that weaving is possible even in the case of high density fabrics.

In general, the movement path of the fabric using the water jet loom is made as shown in Figure 8 and 10.

That is, as the inclination 2 is transmitted from the inclined beam 15, the inclination 2 is opened by the vertical movement of the seed light 3, and the weft of the weft by the injection water is made between the opening inclinations 2, At the same time, the fabric 8 is woven by immersing the weft yarn in which the body 1 is enclosed to the fastener 8 '.

The woven fabric 8 passes through a pellet plate 24 and a temple bar 5 located at the bottom of the fastener 8 'where the wefts are crossed to form the fabric 8. The fabric 8 past the temple bar 5 passes through the dehydration tube 7 located on the top stay 12 and is formed by the dehydration groove 7 ′ drilled in the dehydration tube 7. The water remaining in 8) is dehydrated.

The fabric (8) passing through the dewatering pipe (7) is passed through the upper press roller (9), friction roller (10) and lower press roller (11), and then the fabric winding roller (13). Is wound up.

The weaving device described above is not a problem for weaving fabrics of which the density of the fabric 8 is generally low but causes problems for weaving high density fabrics.

Briefly, the weaving of the fabric (8) is a weft yarn between the opening inclined (2), and the light and weft yarns interweave the vertical yarn and the weft yarn of the heald (3) by the body needle movement, the fabric (8) In this case, if the density of the weft exceeds the basic density, after the forward movement (body) of the body (Reed) (1), when the reversed (Cloth fell) (8 ') the body The tension of the fabric is maintained as it is pushed toward the (1) side, and when the body 1 is advanced again after entering the weft, the fabric 8 is moved backward by the movement of the body 1, that is, The tension is loosened as it is pushed toward the upper press roller 9.

This fabric rumbling phenomenon is called bumping phenomenon.

As described above, the weaving smoothness of the high-density fabric is determined by how quickly the fabric 8 in the tension roller 10 is wound in the friction roller 10 every time the body stitches are wound.

However, in the case of the weaving device as shown in FIG. 8, since the distance from the fastener 8 'to the friction roller 10 is long, there is a difference in the looseness and tension of the tension given to the fabric by the length of the body needle movement. Since it appears badly, the body swelling phenomenon appears severely during body needle movement, and weaving of the dense fabric is not smooth.

In addition, unlike the above, there is also configured a fabric movement path using a water jet loom.

That is, as shown in FIG. 10, the inclination 2 transmitted from the inclination beam 15 passes through the inclination guide roller 17 and the tension roller 4 and passes through the heald 3 and the body 1 in turn. The inclined (2) is opened by), the weft yarn is infiltrated by the sprayed water between the inclined openings (2), and then the body (1) moves forward to make the fabric (8) by weaving the body needle.

The woven fabric 8 is passed through a pelplate 24 and a temple bar 5 at the bottom of the fastener 8 'and a dehydration tube 7 located at the top of the topstay 12 to the fabric 8. The contained water is dehydrated and the dehydrated fabric is passed directly to the friction roller 10 without passing through the upper press roller 9 and then the fabric via the upper press roller 9 and the lower press roller 11. It is wound up by a winding roller 13.

In the case of such a weaving device, the fabric (8) passing through the dehydration container (7) is connected directly to the friction roller (10) without passing through the upper press roller (9), the friction roller (10) from the fastener (8 ') Since the length up to) can be reduced, there is an advantage in weaving a high density fabric than the weaving apparatus of FIG. 8, but the following problems are caused.

That is, the fabric (8) passing through the dehydration pipe (7) is immediately bent to the friction roller (10) and all the tension on the fabric (8) is concentrated in the dewatering pipe (7), so the dehydration pipe (7 ) Should not be bent so that the thickness of the dehydration pipe (7) to be thick, and thus the depth of the dehydration groove (7 ') is deepened, so the dehydration efficiency is reduced.

In addition, since the surface area of the fabric 8 in contact with the dehydration tube 7 becomes wider, when the temperature of the sprayed water for infiltration and the temperature deviation in the workplace are severe, condensation phenomenon appears on the outer surface of the dehydration tube 7 and the dehydration effect is severe. There was also a disadvantage of falling.

As described above, in the weaving apparatus as shown in FIGS. 8 and 10, the moving path, that is, the distance between the fasteners 8 'and the friction roller 10 cannot be reduced as follows.

That is, as shown in FIG. 11, the means for gripping the end cut yarn of the weft and drawing it to the outside is made by a catch cord yarn 2 '.

At this time, as the means for gripping the end of the weft of the catch cord yarn 2 'cut by the cutting machine, the spindle drive shaft 6, the drive pulley 23, the belt 18, It is made by the spindle drive pulley 19, spindle body 20 and spindle (Spindle) (21).

As described above, related parts for the operation of the catch cord yarn 2 'are installed on the top stay 12 positioned below the dehydrating pipe 7, so that the fastener 8' and the friction roller 10 In order to shorten the moving path distance of the fabric 8, the catch cord yarn 2 'related parts must be changed to an uninterrupted position, but it is impossible with existing equipment.

Therefore, the water jet loom currently used cannot shorten the moving distance of the fabric 8 from the fastener 8 'to the friction roller 10. It is the biggest obstacle to weaving fabrics.

In addition, the belt 18 for connecting the related parts for the role of the conventional catch cord yarn 2 ', that is, the drive pulley 23 fitted to the spindle drive shaft 6 and the spindle driven pulley 19 is fastened 8'. Because it is located just after the), the injection water for weft wetting soaks the belt 18 and the driving pulley 23.

Therefore, in order to prevent the belt 18 from slipping due to water, the tension of the belt 18 must be increased. Therefore, an excessive force is applied to the belt 18 and the bearing, thereby shortening the service life and extending the life of the bearing. In order to inject lubricating oil, problems such as contamination of the fabric and slipping of the belt 18 are caused.

In addition, weft detector, weft cutter, temple, etc. are located where the spindle 21 for catch cord yarn operation is located, and the devices must be checked and adjusted frequently, but many devices are located. This narrowness makes work difficult.

The present invention minimizes the bumping phenomenon of the fabric during body needle movement by shortening the distance from the fastener to the friction roller at the time of weaving the fabric using the water jet loom to the maximum. Even in the case of woven or double-woven fabrics, we are able to weave more smoothly.

In order to achieve the above object, the present invention moves the positions of the spindle-related parts for catch cord yarn processing, which interfere with and interfere with the fabric movement path, on the front upper surface of the right frame of the loom, and a pedestal is installed on the top stay. It is possible to support the fabric, but to form a dehydration tube consisting of the upper dehydration plate and the lower dewatering plate in front of the pedestal to enable the dehydration of the water contained in the fabric, if necessary eccentric cam on both sides of the friction roller It is installed, and the operating lever connected to the pedestal on the eccentric cam is installed so that the pedestal is elevated so that the position of the fastener can be elevated to prevent the wear and tear of the body.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of a fabric weaving apparatus using the water jet loom 100, the inclination (W) sent from the inclined beam 130 is drawn out through the guide roller 131 and the tension roller 132 forward By passing the heald 120 and the body 110 in turn, the inclination W is opened by the opening movement of the heald 120, and the weft thread is infiltrated between the opening inclination W, and then the body 110 is advanced. By weaving the weft yarn to the fastener (Cloth fell) (C '), which is the time when the fabric is started, the fabric (C) is the same as conventional.

Summary of the Invention The technical gist of the present invention shortens the path of movement of the fabric C between the friction roller 140 from the front of the fastener C 'as much as possible to make the fabric C move during body needle movement. To minimize this.

First, the parts related to the spindle 200 for the operation of the catch cord yarn C1 positioned on the top stay 150 are placed in front of the right frame of the water jet loom 100 as shown in FIG. 3. The position is moved to be installed on the side cover 101 side.

The pedestal 160 is fixedly installed on the top of the top stay 150 connecting the two sides of the frame 102 of the water jet loom 100, as shown in Figure 2, the woven fabric (C) is the top of the pedestal 160 Pass through, but the top 160 of the pedestal 160 is configured to be round so as not to damage the fabric (C).

The position of the pedestal 160 fixed to the top surface of the top stay 150 is ideally installed as close to the fastener (C ') as possible.

The upper plate 171 and the lower plate 172 are fixedly installed on one side of the pedestal 160 and one upper surface of the top stay 150, respectively, so that the dewatering groove 173 is formed therebetween, so that the rectangular dewatering pipe 170 is formed. ) Is configured.

At this time, the position of the dewatering groove 173 formed between the upper plate 171 and the lower plate 172 is positioned so that the upper end 161 of the pedestal 160 and the tip 151 of the top stay 150 extend on the line. The surface of the fabric (C) to move to the top end 150, the tip 151 through the pedestal 160, the upper end 161 is in contact with the dehydration groove 173, so that the dehydration pipe of the moisture contained in the fabric ( 170) to be made smoothly.

A normal friction roller 140, an upper press roller 180, and a lower press roller 181 are installed on the front side of the dehydrating pipe 170, and a fabric winding roller (Cloth) is disposed below the lower press roller 181. Roller 182 is installed.

At this time, the height of the upper end 161 of the pedestal 160 fixedly installed on the top stay 150 is configured to be slightly lower than the height of the pellet plate (111) supporting the lower end of the fastener (C1) as shown in FIG. The woven fabric (C) is guided in a state inclined by about 7 to 10 ° from the warp line (K), and the fabric (C) past the top stay 150, the tip 151 is friction The roller 140 and the upper press roller 180 and the lower press roller 181 are passed through the fabric winding roller 182 to smooth the weaving of the double fabric.

Installation of the spindle 200 located on the upper surface of the right frame front one side cover 101 of the water jet loom 100 is as follows.

3, the bracket 210 is installed on the cover 101 and the spindle 200 is rotatably installed on the bracket 210, but a driven pulley 220 is installed at one side thereof. The driven pulley 220 rotates the spindle 200 by the belt 250 from a conventional spindle drive pulley (not shown). However, the length of the conventional spindle drive shaft is shortened to be installed inside the right frame.

Therefore, the catch cord yarn C1 via the catch cord yarn guide plate 251 is twisted by the spindle 200 and grips the weft cut by the weft cutter to be guided to the spindle 200, and at the same time, the guide roller ( 230 is withdrawn and collected to the outside through the extraction gear 240.

In the present invention, the cam 141 is installed on both sides of the friction roller 140 as shown in FIG. 4, and the pedestal 160 is lifted by the cam 141 so that the position of the fastener C1 is elevated. By doing so, it is possible to prevent the uneven wear phenomenon of the body 110.

That is, the front support 165 and the rear support 166 is fixedly installed on the top stay 150 to form a space therebetween, and the pedestal 160 is inserted into the space, but the pedestal 160 Abrasion prevention plate 164 is installed between the front and rear support 165, 166 to reduce the friction during the lifting of the pedestal 160 to prevent wear.

In addition, the cam 141 installed on both sides of the friction roller 140 allows the operation ball 168 installed at the bottom of the center of the operation lever 167 to be grounded, but one side of the operation lever 167 has a water jet through the fixing pin 163. It is fixed on the frame 102 of the loom 100, and the other front end portion 169 is connected to the pedestal 160 sandwiched between the front and rear supports 165, 166.

Therefore, when the friction roller 140 rotates and the integrally formed cam 141 rotates, the operation ball 168 in contact with the cam 141 moves up and down to raise and lower the operating lever 167 and the operating lever 167. As the pedestal 160 connected to the tip portion 169 is lifted and lifted, the fabric C located above the pedestal 160 is also lifted, so that the position of the fastener C1 is in contact with only one body 110 during the body needle movement. By doing so, it is possible to prevent the uneven wear phenomenon of the body 110.

At this time, the Temple Bar 115 located at the front of the pedestal 160 and the Fell Plate 111 located at the bottom of the fastener C1 are also lifted together, and the Temple Bar 115 and the Pellet Plate 111 are also lifted. Means for the elevating together is made by a connecting rod 260 fixedly installed on the pedestal 160.

That is, as shown in FIG. 6, the connection table 260 is fixed to one side of the pedestal 160 with the fixing bolt 261, and the temple bar 115 is positioned at the center of the connection table 260, and then as the fastening piece 262. When the pedestal 160 is elevated by fastening and fastening, and inserting the pel plate 111 to the front end and fastening with the bolt 263, the temple bar 115 and the pel plate 111 fixedly installed on the connecting table 260 are fixed. Was to be elevated together.

Unexplained sign.

Reference numeral 300 is a locking shaft, and 310 is a catch cord yarn cutting detector.

The weaving process using the water jet loom 100 of the present invention configured as described above is as follows.

That is, the inclined beam 130 transmits the inclination W so as to pass through the guide roller 131, the tension roller 132, the heald 120 and the body 110, and the inclination after the body 110 is the heald. The warp (W) is opened by the movement of 120, the weft yarn between the opening warp (W) and then the body (110) to advance the body needle movement, the fabric (C) is woven, weaved As the fabric (C) is moved to be wound on the fabric winding roller 182 as in the prior art.

The technical gist of the present invention is to provide a high-density fabric by greatly reducing the slack of the fabric (C) during body needle movement by minimizing the movement distance to the friction roller 140 while the woven fabric (C) moves. In the case of a double-woven fabric, it is possible to weave smoothly.

That is, when looking at the fabric (C) movement path in the present invention, the woven fabric (C) passes through the pellet plate 110 and the temple bar 111 and then moves to the pedestal 160, the fabric in the pedestal 160 It is bent downward again and is moved to the top end 151 of the top stay 150.

At this time, the bottom surface of the fabric (C) is passed while contacting the dehydration groove 173 formed between the upper plate 171 and the lower plate 172 of the dewatering pipe 170, the fabric by the air suction action of the dewatering pipe 170 The water contained in (C) is dehydrated.

The dehydration pipe 170 applied in the present invention does not need a bracket for fixing the dehydration pipe as there is almost no tension load of the fabric, and when the dewatering pipe is used as the conventional, the dewatering pipe is made of a thin pipe. It is possible to use, and it is possible to reduce the production cost because it does not need a bracket for fixing the dehydration pipe installed on the left and right of the frame.

The fabric C, which has passed the front end 151 of the top stay 150, immediately moves to the friction roller 140 and pivots, and then passes through the upper press roller 180 and the lower press roller 181, and then the fabric winding roller 182. ) Is wound up.

At this time, the position of the parts related to the spindle 200 for the catch cord yarn (C1) processing, which is located on the top stay 150 as in the prior art, is completely separated from the top stay 150 and receives no interference of the water jet loom 100. Since the cover 101 is fixed to the upper surface, the interference can be completely avoided, so that the distance of the fabric C to the friction roller 140 can be greatly reduced.

The most important thing in the process of weaving the high-density fabric (C) is to make the woven fabric (C) the shortest moving distance to the friction roller 140, the shorter the distance is advantageous for the high-density fabric and double-woven fabric weaving.

Briefly explaining why the weft crosses the weaving fabric and weaving process (C1) when reversing after the forward movement (body movement) of the body 110 as much as the excess of the basic density (base density) of the weft in the weaving process Is pushed toward the body 110, and when the body 110 is advanced again, the fastener C1 is pushed by the body 110.

That is, when the body 110 is backward, the tension of the fabric C is kept tight, and as opposed to the above, when the body 110 is advanced, the fastener C1 is pushed by the body 110 while being pushed. The tension of the fabric C is loosened.

As described above, weaving of the high density fabric depends on how quickly the friction roller 140 absorbs and winds it in the state in which the tension of the fabric C is loosened.

Therefore, in the present invention, the fabric can shorten the moving path of the fabric as the structure to shorten the distance to move to the friction roller 140, the distance is shortened the portion where the tension is loosened at the most advanced of the body 110 As it is possible to cope with sensitivity as sensitive as possible, the weaving of the high-density fabric or double-woven fabric is to be made smoothly.

In addition, in the case of the present invention, the fabric (C) past the temple bar 115 is bent sharply descending while passing through the pedestal 160 fixed to the top stay 150, and again at the front end portion 151 of the top stay 150 It is bent once more and guided to the friction roller 140.

Therefore, the tension load applied to the fabric C while the fabric C moves is concentrated on the pedestal 160 and the top stay 150, and the fabric movement direction is sharply switched in the two places, thereby causing the tension to move during the fabric movement. The direction of the force is dispersed and the fabric loosened at the most advanced of the body 110, the friction roller 140 can be quickly absorbed and wound up.

The dewatering pipe 170 provided on the top stay 150 is not rectangular, but a circular dewatering pipe conventionally used may be used.

In constructing the water jet loom 100 of the present invention, the position of the parts related to the spindle 200 for catch code yarn C1 processing is moved to the upper surface of the right side frame 101 of the right side of the water jet loom 100. Installed and woven fabric (C) to shorten the movement distance to the friction roller 140 as possible.

The role of the spindle 200 for the catch cord yarn C1 processing is the same as in the related art.

Briefly, the end cut yarn of the weft inserted by the catch cord yarn C1 is gripped, and the held cut yarn moves toward the spindle 200 through the catch cord yarn guide plate 251, and passes through the spindle 200. The catch cord yarn C1 is pulled out by the drawing gear 240 after passing through the guide roller 230.

As described above, the related parts of the spindle 200 for the catch cord yarn C1 are installed on the upper surface of the front cover 101 of the water jet loom 100, and thus, from the jetting water for weft incidence as in the prior art. Since it is not affected, durability of the spindle 200 may be extended, and the sliding phenomenon may be prevented when the spindle 200 is driven by the belt 250.

In addition, since the spindle 200 is moved to the upper surface of the cover 101, the space is secured in the position where the weft detector, the weft cutter, the temple (temple), etc., so as to facilitate repair and handling.

In constructing the water jet loom 100 according to the present invention, as shown in FIG. 4, the cam 141 is installed on both sides of the friction roller 140 so that the position of the fastener C 'is raised and lowered. It can prevent uneven wear.

In more detail, when the friction roller 140 rotates, the cam 141 also rotates together, and the operating lever 167 moves the fixing pin 163 up and down by the rotation of the cam 141.

At this time, the actuating lever 167 is to lift the fixed pin 163 to the shaft because the actuating ball 168 connected to the actuating lever 167 is in contact with the outer peripheral surface of the cam 141, the cam for the friction roller 140 The operating lever 161 is raised and lowered according to the eccentricity of 141.

As described above, when the operation lever 167 is raised and lowered, the pedestal 160 connected to the front end portion 169 of the operating lever 167 is guided and lifted by the front and rear prevention zones 165 and 166 so that the top of the pedestal 160 is elevated. The position of the fabric C passing through 161 is also raised and lowered.

When the fabric (C) located in the upper end 161 of the pedestal 160 is elevated, the position of the fastener (C ') is also elevated, and thus the position where the fastener (C') is in contact with the body 110 is moved up and down. Uneven wear of the body 110 can be prevented.

When the pedestal 160 is elevated, the position of the temple bar 115 and the pel plate 111 supporting the bottom surface of the fabric C is also elevated.

That is, the temple bar 115 and the pel plate 111 are fixedly installed on the connecting table 262 fixedly installed on the front of the pedestal 160. When the pedestal 160 is elevated, the connecting bar 260 is also raised, and thus, the connecting table 260. Temple bar 115 and the fixed plate 111 fixedly installed on the) is also lifted with the fabric (C), so weaving according to the lifting of the fastener (C ') is not a problem.

As described above, in the present invention, in constructing the fabric weaving device using the water jet loom, the spindle position for catch cord yarn processing is moved on the one side cover of the front right frame of the water jet loom, and thus, Also, there is no problem in weaving high-density fabrics or double-woven fabrics by minimizing the bumping phenomenon of the fabric during body needle movement by making the shortest distance the woven fabric moves to friction roller. There is no effect, such as to more effectively perform the dehydration of the water contained in the fabric.
